1881.] COLKOPTERA FROM ECUADOR. 263 



The head, the middle of the sterna and the middle of the hase of 

 the abdomen are reddish yellow. The legs are yellow, with the base 

 of the tibiae dusky. 



15. Cephalolia FELIX, n. sp. (Plate XXX. fig. 8.) 



C. elongata, angusta, flavo-rufa, nitida; antennis nigris, apice 

 flavis, elytris sutura apicein versus marginibusque nigris, corpore 

 subtus pedibusque rufo-flavis. 



Long. 1% lin. 



Antennae moderately long, the three apical joints yellow ; the 

 third joint nearly twice as long as the second. Head with a small 

 impression on the vertex. Thorax a very little wider than the head, 

 a Uttle broader than long, parallel, convex, with an impression on 

 each side of the basal median lobe, not very closely but strongly 

 punctured, with a narrow smooth median line ; the front margin 

 moderately arched ; the anterior angles obtuse, and not so far ad- 

 vanced as the front margin ; the sides straight, finely margined ; 

 the posterior angles a trifle greater than right angles ; the basal 

 lobe rather broad, and somewhal; straight near the scutellum. Elytra 

 nearly twice as broad as the thorax, elongate, a little broader before 

 the apex than at the base, slightly impressed in the middle of the 

 base, strongly punctate-striate, the striae near the base only indicated 

 by a few punctures, the interstices narrow and rather elevated ; the 

 margins (commencing below the shoulders) and the suture for half 

 its length are black. 



This species is closely allied to the preceding, both being of nearly 

 the same form, agreeing in having the apex of the antennae pale. 

 They appear to be most nearly allied to C.javeti, Baly, but are still 

 very distinct. 



16. Cephalolia angusticollis, n, sp. (Plate XXX. fig. 4.) 



C. vigra nitida; thorace vix marginato, puree pimctato. 



Long. 2| lin. 



Head narrow, with a fine median frontal ridge, which terminates 

 between the antennae in a minute, acute point ; the internal margin 

 of the eye is acutely raised. Thorax much narrower than the elytra, 

 very little broader than long, convex, parallel, moderately strongly 

 and somewhat sparingly punctured ; the sides and anterior border 

 extremely finely margined ; the base only margined in the middle ; 

 the anterior angles rounded, the posterior slightly acute. Scutellum 

 smooth, a little narrower at the base than across the middle, not 

 very acute at the apex. Elytra subparallel, not much narrowed 

 towards the apex, with lines of distinct punctures ; there is a strongly 

 impressed sutural stria, which, however, does not extend to the base 

 of the elytra; the apex is very obtuse; on the lateral margin, a 

 little below the shoulder, there is a distinct but shallow elongate 

 impression. 



This species is certainly congeneric with Cephalolia angustata, 

 Guerin, but differs specifically from it in being of a rather broader 

 form, &c. Both these insects resemble the species of the genus
